Working Principle

The TPS61121RSARG4 device is a power management integrated circuit (PMIC) designed with an analog core and digital control logic. The analog core is composed of a step-down converter and a low-dropout (LDO) regulator. The step-down converter portion is responsible for generating a regulated output voltage from an input voltage. The LDO regulator then follows the step-down converter portion to regulate and maintain the output voltage.

The device includes different protection mechanisms that protect the system against low input voltage, overvoltage, overcurrent, and overtemperature conditions. It is composed of a theraprotective diode and a high-speed transient voltage suppressor (TVS) that protect the system from overvoltage and surge events. The device also includes a circuit breaker and a fast-acting current limit function that provide protection from overcurrent and overtemperature events. Additionally, the device can be configured with a single digital input that can be used to turn the device on and off.
